Sonic Toothbrush for Adults

The Bymore M306 is a rechargeable sonic toothbrush designed for adults seeking a complete daily oral-care routine. It operates with five automatic cleaning modes and a built-in two-minute timer that paces every 30 seconds. The handle is powered by an internal lithium-ion battery and has an IPX7 waterproof rating for safe bathroom use.

70-Day Battery and 8 Brush Heads

A single charge delivers up to 70 days of regular brushing, reducing the need to carry a charger on short trips. The package includes eight DuPont replacement heads, four U-shaped and four W-shaped, covering roughly 18 months of use before new heads are required. Fading reminder bristles signal when a change is due.

USB-C Charger and Travel Handle

The box supplies a USB-C charging cable and a portable handle that keeps the brush and spare heads organised while travelling. These accessories let you maintain the same cleaning modes and timer discipline away from home without packing extra adapters or cases.

Questions about this item

Will the 5 modes and 2-minute timer work the same way if I keep using my old manual toothbrush for travel?

The M306 has five built-in modes — Whitening, Clean, Sensitive, Polish, Massage — each with a 2-minute timer and 30-second pacing, so the brush itself keeps the routine consistent even if you switch brushes.

How can I tell the sonic vibration is still strong after a few weeks of use?

The brush runs on a rechargeable lithium-ion battery rated for 70 days per charge; if the vibration feels weaker before then, the battery likely needs recharging.

What comes in the box and what do I need to buy later?

The package includes the black M306 handle, 8 DuPont brush heads (4 U-shaped, 4 W-shaped), a USB-C charger, and the internal battery; replacement heads are the only item you will need to purchase separately.
